Characteristics

Shrub or small tree 1–3(–4.5) m. tall, occasionally weak and almost trailing; stems glabrous, the bark peeling in long strips on older stems.. Leaf-blades elliptic, oblong-elliptic or lanceolate, 2–11.5(–19) cm. long, 1–4.2 (–4.5) cm. wide, ± acute, the actual apex± obtuse, less often acuminate (in some cultivated specimens), cuneate to subcordate at the base, thinly coriaceous, glabrous, often with pale minute white specks particularly near the midrib above; petiole 5–9 mm. long; stipules triangular, 2.5–4 mm. long, keeled, glabrous.. Inflorescences sessile or practically so, the two opposite together forming a globose cluster up to 1.5 cm. diameter or peduncles up to 4 mm. long in one variant; components quite glabrous outside or almost imperceptibly puberulous; bracteoles cupular, tightly surrounding the calyx-base, ± 1 mm. tall.. Calyx shallowly cup-shaped, 1.5(–2) mm. long, glabrous outside or imperceptibly puberulous or in one variant silky pubescent, glabrescent to densely pubescent inside, often with pale marks outside, usually truncate, sometimes undulate or faintly toothed or becoming lacerate.. Flowers sweetly scented; corolla white; tube (2–)4 mm. long, glabrous outside or adpressed puberulous in one variant, densely white hairy at the throat; lobes ovate, 1.5–2 mm. long and wide.. Style densely white hairy; disc prominent.. Fruits globose, 7–9 mm. diameter, glabrous, ± white-dotted, somewhat didymous.. Seeds ± semiglobose, ± 6 mm. long, 4 mm. wide.

Leaves 2–11.5(15.5) × 1–4.2(4.7) cm, elliptic, oblong-elliptic or lanceolate, ± acute, the actual apex ± obtuse, less often acuminate (in some cultivated specimens), cuneate to subcordate at the base, thinly coriaceous, glabrous, often with pale minute white specks particularly near the midrib above; petiole 5–9 mm long; stipules 2.5–4 mm long, triangular, keeled, glabrous.
Inflorescences sessile or practically so, the two opposite together forming a globose cluster up to 1.5 cm in diameter, or peduncles up to 4 mm long in one variant; components quite glabrous outside or almost imperceptibly puberulous; bracteoles cupular, tightly surrounding the calyx base, c. 1 mm tall.
